The SN55LBC976 is a 9-channel differential transceiver based on the SN55LBC176 LinASICE cell. Use of TI's LinBiCMOSE† process technology allows the power reduction necessary to integrate nine differential transceivers. On-chip enabling logic makes SN55LBC976 applicable for the data path (eight data bits plus parity) and the control path (nine bits) for both the Small Computer Systems Interface (SCSI) and the Intelligent Peripheral Interface (IPI-2) standard data interfaces.
The switching speed and testing capabilities of the SN55LBC976 are sufficient to transfer data over the data bus at 10 million transfers per second. Each of the nine channels conforms to the requirements of the ANSI RS-485 and ISO 8482:1987(E) standards referenced by ANSI X3.129-1986 (IPI), ANSI X3.131-1993 (SCSI-2), and the proposed SCSI-3 standards.
The SN55LBC976 is characterized for operation from 55 to 125 .
